Inserts Taking Longer Time

Hello All,

I have SQL Server 2005 installed on my machine and I am firing following query to insert 1500 records into a simple table having just on column.

Declare @i int
Set @i=0
While (@i<1500)
Begin
Insert into test2 values (@i)
Set @i=@i+1
End

Here goes the table definition,

CREATE TABLE [dbo].[test2](
[int] NULL
) ON [PRIMARY]

Now the problem with this is that on one of my server this query is taking just 500ms to run while on my production and other test server this query is taking more than 25 seconds.
Same is the problem with updates. I have checked the configurations of both the servers and found them to be the same. Also there are no indexes defined on either of the tables. I was wondering what can be the possible reason for this to happen. If any of u people has any pointers regarding this, will be really useful

Thanks in advance,
Mitesh
